INDIANAPOLIS - IndyGo is making plans to expand its fleet of electric hybrid buses.

The Indianapolis public transportation service recently received a $19 million Federal Transit Administration grant.

IndyGo said this week it will put grant funds toward replacing older buses in its fleet with electric hybrid propulsion buses produced by Allison Transmission Inc. and GILLIG.

The 40-foot Allison eGen Flex system buses can operate up to half of a bus’ route in “engine-off mode,” according to a release from the Indianapolis-based manufacturer.

The electric-only function is activated by geofencing technology, cutting engine emissions and noise off during passenger drop-off and pick-up. It may also kick on in dense pedestrian areas and zero-emission zones.

Allison officials say IndyGo’s current fleet of electric hybrid buses have saved more than 20,000 metric tons in carbon dioxide emissions as well as more than 2 million gallons of diesel fuel.

“We’re honored to play a critical role in advancing clean public transportation in Indianapolis and supporting IndyGo’s sustainability goals,” Allison Vice President of North America Sales Rohan Barua said in a news release. “Allison has been manufacturing electric hybrid propulsion solutions for the transit market for nearly 20 years, and we remain committed to collaborating with transit agencies nationwide to support them in their transition to net-zero emissions technology.”
